The RD90 device is a colour victim location camera, waterproof to 90 m (also called 'optical instrument') designed to visually locate a person trapped in a deep enclosed space (well, tunnel, mine, etc.). Waterproof, the RD90 camera can be submerged in water to a depth of 90 m, enabling reconnaissance of deep flooded environments. It can be lowered into wells, caves, crevices or under water for all types of inspections by divers up to 90 m below the water level.

The RD90 search camera is a colour camera attached to a 90 m cable wound onto a reel. The RD90 camera head is fixed, meaning it is enclosed in a very strong casing providing a 90° field of view. It is waterproof to a depth of 90 m to enable investigations in very wet or underwater environments. It is also fitted with LEDS with 8 intensity levels. The camera lens is protected by a scratch-resistant sapphire crystal glass. Optional 25 m and 90 m extension leads (orange, abrasion-resistant cable) can be lowered to a depth of up to 180 m to inspect caves, crevices or wells.
